Beach morning glory

Plant | Convolvulaceae
Ipomoea pes-caprae


The beach morning glory is a common costal plant on the sandy shores of Taiwan. It has saddle-shaped leaves and purple trumpet-shaped flowers. Because the beach morning glory is a coastal vine and can withstand draught and salinity, it is used to stabilize sandy soils. Its thick leaves are covered in a layer of wax and have few stomata, enabling it to reduce water loss under the hot sun. The saddle-shaped leaves can also curve to prevent direct sunlight. All these features have made the beach morning glory a dominant species in sandy shores.


The beach morning glory grows in the core area of Gaomei Wetlands beside the Fanziliao Levee.
